Background Footwear with a curved sole profile has become popular due to the proposed benefits to gait, posture and altered muscle activity and tone. In addition, rocker profiled footwear are one of the most commonly prescribed therapeutic shoes [1-4]. The altered movement of the body over the foot due to the curved sole profile is assumed to alter the position of the hips and thereafter the tr...

The article discusses the choice of power and type drive motor for system controlling vibration amplitude rectifier rocker arms continuously variable mechanical transmission, intended use on a vehicle. Formulas calculating required torque rotational speed with planetary differential control gear are given. It is shown that an electrohydraulic provides operation system. results testing presented.

A 2 month old infant presented with bilateral subdural haemorrhages and bilateral subhyaloid haemorrhage. The parent admitted to forceful bouncing of the child in a baby rocker. Experiments showed that violent rocking in the chair could produce extreme alternating acceleration/deceleration forces in excess of those induced by shaking alone. Such handling could not be interpreted as accidental m...

OBJECTIVE The overall objective was to unfold the phenomenon of interrater agreement: to identify potential sources of variation in agreement data and to explore how they can be statistically accounted for. The ultimate aim was to propose recommendations for in-depth examination of agreement to improve the reliability of assessment instruments. STUDY DESIGN AND SETTING Using a sample where 10...

A vertical talus is one feature of the rare congenital abnormality known as congenital convex pes valgus (Lamy and Weissman 1939), or rocker-foot (Hark 1950). Two cases of vertical talus deformity are described here associated with severe burn contractures. The position of the contractures suggests that the scarring is responsible for the deformities. If this is so, does the acquired abnormalit...

Abstract Robotic rovers equipped with articulated rocker-bogie suspension have aroused great interest after the explorations on Mars; this has also shifted to different types of terrestrial applications such as in agriculture, military, and rescue fields. The can be designed so that, when rover is flat horizontal ground, weight evenly distributed among wheels; way, all wheels same traction capa...
